The name Fabrice Bellard may not be recognizable to a lot of people, but the work he carries out as a programmer and computer scientist is. . . . He is a very talented programmer, and his latest project demonstrates once again just how talented he is. Using the super-fast JavaScript engines that now come as standard in popular web browsers, he has managed to create a PC emulator that runs in a browser. As a demonstration he has posted a link to a version of the Linux kernel running in such a scenario.
